Notes: The master plan calls for parcels 17A and 17B to be combined, shortening Broad Street by a block by eliminating what is known as Broad Street Extension. The combined parcels are the only ones the master plan designates for a grass lawn of substantial size. The master plan also calls for a café and a small cultural facility and notes that this is one area in which it might be possible to build something -- perhaps a small cultural or educational facility -- below ground. A partnership of Combined Jewish Philanthropies and Jewish Community Centers of Greater Boston has said it may put together a plan for a cultural and arts center on the site.
